Utility for printing resolved implicit chain

[jatcwang]

I recently was debugging implicit resolution issues and I found it quite useful to print out the fully resolved implicit chain

This is the basic implementation I had:

import scala.quoted.* inline def printResolvedImplicit[A]: Unit = ${ printResolvedImplicitImpl[A] } private def printResolvedImplicitImpl[A](using quotes: Quotes, t: Type[A]): Expr[Unit] = import quotes.reflect.* Expr.summon[A].match { case Some(ex) => println(ex.asTerm.show(using Printer.TreeCode)) case None => report.error("Implicit resolution failed") } '{ () } 

Does something exist in the Scala 3 std lib? Is it useful enough to be included?
